SYNOPSIS

**notmuch** **dump** [--format=(batch-tag|sup)] [--] [--output=<*file*>] [--] [<*search-term*> ...]
**notmuch** **dump** [--gzip] [--format=(batch-tag|sup)] [--output=<*file*>] [--] [<*search-term*> ...]
DESCRIPTION
===========
@ -19,52 +19,58 @@ recreated from the messages themselves. The output of notmuch dump is
therefore the only critical thing to backup (and much more friendly to
incremental backup than the native database files.)
``--gzip``
Compress the output in a format compatible with **gzip(1)**.
See **notmuch-search-terms(7)** for details of the supported syntax
for <search-terms>. With no search terms, a dump of all messages in
the database will be generated. A "--" argument instructs notmuch that
the remaining arguments are search terms.
``--format=(sup|batch-tag)``
Notmuch restore supports two plain text dump formats, both with one
message-id per line, followed by a list of tags.
Supported options for **dump** include
**batch-tag**
The default **batch-tag** dump format is intended to more robust
against malformed message-ids and tags containing whitespace or
non-\ **ascii(7)** characters. Each line has the form
``--gzip``
Compress the output in a format compatible with **gzip(1)**.

``--format=(sup|batch-tag)``
Notmuch restore supports two plain text dump formats, both with one
message-id per line, followed by a list of tags.
Tags are hex-encoded by replacing every byte not matching the
regex **[A-Za-z0-9@=.,\_+-]** with **%nn** where nn is the two
digit hex encoding. The message ID is a valid Xapian query,
quoted using Xapian boolean term quoting rules: if the ID
contains whitespace or a close paren or starts with a double
quote, it must be enclosed in double quotes and double quotes
inside the ID must be doubled. The astute reader will notice
this is a special case of the batch input format for
**notmuch-tag(1)**; note that the single message-id query is
mandatory for **notmuch-restore(1)**.

**sup**
The **sup** dump file format is specifically chosen to be
compatible with the format of files produced by sup-dump. So if
you've previously been using sup for mail, then the **notmuch
restore** command provides you a way to import all of your tags
(or labels as sup calls them). Each line has the following form

(malformed) message-ids may contain arbitrary non-null
characters. Note also that tags with spaces will not be
correctly restored with this format.
